The present invention provides compositions and methods to facilitate the identification of compounds that are capable of interacting with a biological macromolecule of interest. In one aspect, a composition is provided that comprises an array of one or more types of chemical compounds attached to a solid support, wherein the density of the array of compounds is at least 1000 spots per cm<2>. In particularly preferred embodiments, these compounds are attached to the solid support through a covalent interaction. In general, these inventive arrays are generated by: (1) providing a solid support, wherein said solid support is functionalized with a selected chemical moiety capable of interacting with a desired chemical compound to form an attachment; (2) providing one or more solutions of one or more types of compounds to be attached to the solid support; and (3) delivering said one or more types of compounds to the solid support, whereby an array is formed and the array of compounds has a density of at least 1000 spots per cm<2>. In another aspect, the present invention provides methods for utilizing these arrays to identify small molecule partners for biological macromolecules of interest comprising: (1) providing an array of compounds, wherein the array has a density of at least 1000 spots per cm<2>; (2) contacting the array with one of more types of biological macromolecules of interest; and (3) determining the interaction of specific small molecule-biological macromolecule partners.
